The LM2576HVSX-ADJ/NOPB from Texas Instruments is a monolithic integrated circuit designed as a step-down (buck) DC DC switching regulator. It is part of the SIMPLE SWITCHER family, known for its low component count.
This regulator features an adjustable output voltage ranging from 1.23V up to 37V (or 57V for HV versions), with a maximum tolerance of ±4% over line and load conditions. It can supply a continuous output current of 3A. The device operates over a wide input voltage range, from 4V up to 60V for the HV variant. It utilizes a fixed internal oscillator operating at 52kHz.
The LM2576HVSX-ADJ/NOPB is available in a TO-263-5 surface mount package (DDPAK/TO-263-5). The operating temperature range is -40°C to 125°C (TJ). This component requires only four external components for operation, simplifying design and reducing board space.
This regulator is suitable for various power management applications where a stable, adjustable output voltage is required from a higher input voltage source. Its high efficiency and simple external component requirement make it a practical choice for designs needing a robust step-down conversion.
